Abstract
An optical arrangement for disinfection in apparatuses operating with air or a liquid comprises at least one radiation source or at least one group of radiation sources, which emits or jointly emit radiation in the ultraviolet wavelength range, at least one beam collecting optical unit, which collects the radiation emitted by the radiation source or the group of radiation sources, a number of beam delivering optical units, each configured to receive the radiation collected by the at least one beam collecting optical unit, and also a number of effect zones spatially separated from one another, into which the radiation delivered via the beam delivering optical units is emitted in order to bring about a disinfecting effect.
Claims14
An optical arrangement for disinfection in apparatuses operating with air or a liquid, comprising:
- at least one radiation source or at least one group of radiation sources, which emits or jointly emit radiation in the ultraviolet wavelength range;
- at least one beam collecting optical unit, which collects the radiation emitted by the radiation source or the group of radiation sources;
- a number of beam delivering optical units, each configured to receive the radiation collected by the at least one beam collecting optical unit;
- and
- a number of effect zones spatially separated from one another, into which the radiation delivered via the beam delivering optical units is emitted in order to bring about a disinfecting effect;
- wherein
- the at least one radiation source or the at least one group of radiation sources, the at least one beam collecting optical unit and/or the number of beam delivering optical units are/is configured such that the radiation emitted by in each case a single radiation source can be delivered to at least two of the effect zones spatially separated from one another simultaneously or with a temporal spacing in each case;
- the at least one radiation source or the at least one group of radiation sources is assigned in each case to a beam collecting optical unit and together with the latter forms a unit, and
- the unit comprising the at least one radiation source or the at least one group of radiation sources and the respective beam collecting optical unit, on a common mount, is configured as movable between the beam delivering optical units, such that depending on a selection of an effect zone to be disinfected the unit can interact with one of the beam delivering optical units.

- a number of effect zones spatially separated from one another, into which the radiation delivered via the beam delivering optical units is emitted in order to bring about a disinfecting effect;
- and
- a rotatably configured mirror, which, depending on a tilting, delivers the radiation collected by the beam collecting optical unit optionally to one of the beam delivering units;
- wherein
- the at least one radiation source or the at least one group of radiation sources, the at least one beam collecting optical unit and/or the number of beam delivering optical units are/is configured such that the radiation emitted by in each case a single radiation source can be delivered to at least two of the effect zones spatially separated from one another simultaneously or with a temporal spacing in each case, and
- the rotatably configured mirror is a hollow-cylinder-segment-shaped reflector configured as rotatable in particular about its center axis, which reflector simultaneously forms the beam collecting optical unit in relation to the radiation source and also the beam delivering optical unit assigned to the beam collecting optical unit, wherein the radiation source itself emits radiation in a full circle of 360° in a plane perpendicular to the center axis.
